You guys should post those in the Nostalgic Hardware thread as well.
I remember those OCZ RAM coolers, Cold Storm had one and decided he didn't need it anymore so I ripped out the 60mm fans. One is cooling the insides of my tube amp and the other is cooling my VRMs on the R4E. Pretty good airflow for 60mm and low noise. The one in my amp is running at roughly 6.5v and still putting out decent air flow(enough to cool the transformer and tubes and then blow that hot air out the side vents)
